CAP-SPINNING AND' cAr-TWrsrING vMACHINE Specification of Letters Patent.

Application led November 19, 1914. Serial No. 872,920.

To all whom it may concern Be it known that I, JOHN HoDcsoN, a citizen of the United States, and a resident of Cleveland, in the county of Cuyahoga and State of Ohio, have invented certain new and useful Improvements in Cap-Spinning and Cap-Twisting Machines, of which the following is a specification.

The invention pertains more particularly to the spindle accessories present in cap spinning and cap twisting machines, my invention having for its object to improve the eifrciency and effect economy in the use of the machines but not involving any change in the structure thereof other than in the accessories applied to the various spindles of the machines.

Ordinarily there are about one hundred spindles on each side of a cap spinning machine and usually about one-half that number of spindles on each side of a cap twisting machine,y and upon each spindle, which is adjustably secured to a proper support, is disposed a cap, a bobbin for the worsted or silk yarn, a whirl or pulley below and keyed to the bobbin and a washer below the whirl or pulley and seated upon a lifterplate through which all of the spindles eX- tend and which is adapted to have a proper vertical movement for effecting the elevation and lowering` of the bobbins on the spindles, saidbobbins usually being mounted upon metal tubes or sleeves positioned on the spindles and connected with the aforesaid whirls or pulleys.

My invention does not modify the construction of the spindle, cap, bobbin, whirl, metal tube connected therewith and extending through the bobbin or the lifter plate, but resides in a novel construction of what may be called, for convenience, a disk or washer for application to the spindle between the lifter plate and whirl or pulley.

The washer which has heretofore been employed on the spindles below the whirl Y or pulley has' been the ordinary flat washer or flat disk with a hole in the center through which the spindle passed, `and although many difficulties have arisen due to the use of the ordinary flat washer, no adequate means so far as I have any knowledge, has heretofore been provided to remedy the same. Among the objections incident to the .employment of .the flat washer, it may be tween the whirl or pulley and washer with a resulting loss of power and a tendency to create lack of uniformity in the rotation of the bobbins, this latter being a matter of serious consequence in the eiiiciency of the machine. Another objection that has been experienced in connection with the use of the fiat washer resides in the impossibility of properly oilin'g the spindle. The customary method heretofore of applying oil to the spindle was to stop the machine and manually raise the fiat disk washer, with its superposed parts, and squirt the oil below it, whereupon the operator would release Vthe washer to descend, with the result that the washer andv weight above; it would spatter the oil from the lifter plate to such an extent that the floor about these machines became very considerably soiled; The oil thus in lieu of performing its expected duty was in large measure wasted and the spindle was inadequately lubricated. A still further objection to the use of the fiat disk washer below the whirl or pulley is that lint or waste threads gather' between the washer and whirl or pulley and without being promptly or readilyv observed finally causes the whirl and tube, with the bobbin on the tube, to remain up instead of following the lifter-plate back, and this as may be well understood results in imperfections in the yarn.

The objectjof lmy invention is to remedy all of the foregoing and other objectionable conditions and to provide a disk or washerl below the whirl or pulley of such special construction-as to insure proper and convenient lubrication of the spindle, an absence of awaste of oil and uniformity in the rotation of the bobbin, and at the same time permit the application of the lubricant to the spindle without stopping the machine.

The disk or washer provided by me has a central opening through which the spindle passes, a recess in the lower side containing a pad of felt or the like which rests upon the lifter-plate, a dished or concaved upper side 'to receive and direct the lubricant to the opening through the disk or washer, and lugs upon which the lower end of the whirl or pulley may be supported, said lugs affording a limited surface for engagement with the lower end of the whirl or pulley and hence reducing the friction between the parts to a minimum.` The lugs at the upper side of the disk or washer preferably project above the horizontal plane of the washer, leaving the dished or concaved end of the latter accessible both for oiling pur-` presented, reference being had to the accompanying drawings, in which:

Figure 1 is a vertical section through a portion of a cap spinning machine or cap twisting machine embodying my invention, the section being` through the vertical center line of one of the spindles of the machine, the spindle however being shown in elevation; Fig. 2 is a detached top view of the washer or disk embodying my invention; Fig. 3 is a bottom view of the same, and Fig. 4L is a vertical section through the same on the dotted line 4 4; of Fig. 2. Y l

In the drawings 10 designates one of the customary spindles of a cap spinning or cap twisting machine of usual construction, 11 the customary support therefor, 12 a cap on the upper end of said spindle, 13 the usual lifter plate, 14 thebobbin, 15 the whirl or pulley keyed to said bobbin and adapted to receive the customary belt for eecting the rotation of the bobbin, 16 a metal tube or sleeve connected with the pulley or whirl 15 and extending through the bobbin, and 17 a washer or disk mounted on the spindle and lifter plate and supporting the pulley or whirl 15 with the parts connected therewith. All of the parts referred to with the eXception of the'washer or disk 17 are of customary construction, my invention residing `more particularly in the provision of the washer or disk 17 possessing special characteristics and advantages.

` The disk or washer 17 may be made of any suitable metal or material and is preferably circular in horizontal outline, and said disk or washer is formed with a vertical central opening 18, a shallow but otherwise commo dious recess 19 in its bottom, a dished or concaved upper surface 2O leading to said opening 18, and transversely disposed lugs 21 which extend from theupper outer edges of the washer to the opening 1S and project above the horizontal plane of the body of the washer, as shown in Fig. 1, and afford a support for the whirl or pulley 15 and parts mounted thereon, saidwhirl or pulley 15 at its lower edges resting and during its rotation turning on the lugs 21. I illustrate the washer 17 as having two supporting lugs 21 for the whirl or pulley 15 and I have amply demonstrated in practical use that two lugs 21 are sufiicient for the support of the whirl or pulley. The number of lugs 2l may, however, beincreased without departing from the spirit of the invention, but I prefer to employ only two lugs 21, since less friction is developed between the lower end of the whirl or pulley 15 and the washer when said washer is formed with only two lugs 21. The whirl or pulley 15 is rotated at very high speed and hence it is desirable and one of the purposes of my invention to reduce the friction between said whirl or pulley and its supporting washer to the minimum. Within the recess 19 provided in the lower surface of the disk or washer 17, is placed a disk 22 of felt or the like, said disk being apertured in line with the opening 1S in the washer and said washer and disk at the openings therein being strung upon the spindle 10 and seated upon the lifter-plate 13. The disk or washer 17 possesses many advantages in practical use in cap spinning and cap twisting machines.

One of the very great advantages in the use of my invention is that the oil for lubrication may be properly applied and not wasted, by being poured into the concavity 20 at the upper side of the disk or washer 17 the oil flowing down the surfaces of said concavity and reaching the spindle 10 and the disk of felt 22 held within the recess in the bottom of the said disk or washer, the disk 22 absorbing and holding a quantity of the oil and lubricating the spindle 10 during the upward and downward movements of the lifter-plate 13. The vertical movements of the lifter plate 13 are gradual, and hence the concaved or dished upper surface 20 of the disk or washer 17 permits of the oil or lubricant being applied to the spindle without stopping the machine and serves to direct the lubricant to the opening in the disk or washer and against the spindle. The special formation of the upper side of the disk or washer 17 also exposes a given portion of the spindle between the whirl or pulley and disk or washer and this exposure, together with the slight contact between the whirl or pulley and washer results in any lint or thread which might gather below the whirl or pulley being detected with promptness and also in a lack of tendency of the lint or waste threads to gather below the whirl or pulley, as well as in a saving of power due to a reduction in friction between the moving parts.

What I claim as my invention and desire to secure by Letters-Patent, is:

1. In a machine of the character described, in combination with the cap spindle,

whirl, bobbin and lifter plate, a disk or washer on said spindle and plate and supporting the whirl, said disk or washer having a central vertical opening to receive the spindle, a dished upper surface leading from its outer edges downwardly directly to said central opening and transverse lugs extending upwardly from and above the body of the disk or washer to receive and support said whirl, said lugs extending from the edges of the disk or washer inwardly to the vertical plane of said opening and holding the whirl elevated sufficiently above the body of the disk or washer to expose the concave L upper portion thereof and permit the introduction of oil to said concave portion without stopping the machine or elevating the whirl from the washer or the washer from said plate, and said lugs also being extended laterally beyond the lower end surface of the whirl resting on them.
